Nextant 400XT vs Nextant 400XTi

Overview

The Matchup

Same DNA, different refinement. The 400XT proved the remanufactured jet concept. The 400XTi refined it with a better cabin, raked winglets, and autothrottle. Both share the same Williams engines, the same Pro Line 21 avionics, and the same Beechjet 400A foundation. For most buyers, the answer is yes — but let's look at the numbers. The acquisition market references below use dated research.

Specifications

Head to Head

Range
Nextant 400XT2,003 NM (NBAA IFR)
vs
Nextant 400XTi2,003 NM (NBAA IFR)

Identical range. The XTi's raked winglets improve efficiency slightly, but the published range figures are the same.

Max Speed
Nextant 400XTMach 0.78 (447 ktas)
vs
Nextant 400XTiMach 0.78 (447 ktas)
Cabin Width
Nextant 400XT4 ft 11 in ★
vs
Nextant 400XTi~5 ft 2 in (with composite shell)

Three inches wider at shoulder level. The XTi's new composite interior shell is the single biggest improvement over the XT. In a light jet, three inches of shoulder room is the difference between "adequate" and "comfortable."

Cabin Length
Nextant 400XT15 ft 6 in
vs
Nextant 400XTi15 ft 6 in
Cabin Height
Nextant 400XT4 ft 9 in ★
vs
Nextant 400XTi~5 ft 0 in (with composite shell)

2.5 inches more headroom. Again, the composite shell creates a meaningfully better cabin envelope.

Passengers
Nextant 400XT6–8
vs
Nextant 400XTi6–7
Ceiling
Nextant 400XT45,000 ft
vs
Nextant 400XTi45,000 ft
Takeoff Distance
Nextant 400XT3,818 ft
vs
Nextant 400XTi3,818 ft
Landing Distance
Nextant 400XT2,845 ft
vs
Nextant 400XTi2,845 ft
Engines
Nextant 400XT2× Williams FJ44-3AP (3,050 lbs each) with FADEC ★
vs
Nextant 400XTi2× Williams FJ44-3AP (3,050 lbs each) with FADEC + autothrottle

Same engines, but the XTi adds autothrottle — a meaningful operational upgrade that reduces pilot workload, optimizes fuel burn at cruise, and enhances safety during approach and go-around.

Verdict

Which One Wins?

Best for Cabin Comfort

400XTi

Three inches wider, 2.5 inches taller, better noise insulation. The composite interior shell transforms the cabin experience. On a 2-hour flight with 4 passengers, the XTi is noticeably more comfortable.

Best for Pilot Workload

400XTi

Autothrottle is a genuine safety and efficiency improvement. It optimizes thrust settings, reduces workload during critical phases, and saves fuel. Pilots universally prefer the XTi.

Best for Acquisition Value

These retain their different source dates and measurement bases. Public asking examples, model-wide valuations and production positions are not interchangeable achieved sale prices. Aircraft age, condition and maintenance commitments can outweigh an apparent model-level price advantage.

Best Overall

400XTi

The improvements are real and meaningful. The wider, taller cabin and autothrottle justify the premium for most buyers, especially those planning to hold the aircraft for 5+ years.

Bottom Line

The Final Take

The 400XTi is the better buy for most operators. The composite interior shell adds genuine comfort — three inches of shoulder room and 2.5 inches of headroom transform the cabin from adequate to comfortable. The autothrottle reduces pilot workload and saves fuel. And the raked winglets, while more aesthetic than transformational, improve efficiency at the margins. Market research reviewed October 8, 2026: Nextant 400XT: $1.395M–$1.5M asking — two XT examples; Nextant 400XTi: $1.995M asking — 2015 SN RK-129. These retain their different source dates and measurement bases. Public asking examples, model-wide valuations and production positions are not interchangeable achieved sale prices. Compare aircraft of similar vintage and maintenance position before inferring a model premium.
